Fig. 3 is a schematic view of the internal structure of the print head shown in fig. 1. Referring to fig. 1, 2 and 3, the print head of the present embodiment includes:
a hopper 100;
a drive mechanism comprising: a motor 210 and a speed reducer 220 connected to the front end of the motor;

the motor is decelerated by the speed reducer to drive the auger shaft 320 of the stirring auger and the pump shaft of the rubber sleeve screw pump to rotate, the stirring auger is used for stirring the materials in the hopper, and the rubber sleeve screw pump is used for extruding the materials.
The following describes each component of the print head of the present embodiment in detail.
The hopper 100 is used for caching materials transmitted by the feeding mechanism, and the main body of the hopper is made of rustproof and corrosion-resistant 304 stainless steel materials. Fig. 4 is a side view of a hopper portion of the print head of fig. 1. Referring to fig. 1, 2, 3 and 4, the hopper is divided into two parts from top to bottom: a cylindrical material accommodating part 110 and a conical stirring part 120. The material containing part 110 is cylindrical, so that the maximum material storage per unit volume is achieved. The stirring part 120 is in a cone shape, which is beneficial to the cement material to flow to the middle and avoids the cement around from condensing due to no flow for a long time.
In addition, with continued reference to fig. 1, 2, 3 and 4, above the material containing portion, there is also provided a feeding connection portion 130 through which a feeding pipe 150 is connected to the hopper, so as to convey the material to the hopper.

The lower part of the feeding connecting part is connected with the material containing part 110 of the hopper in a direct insertion mode, so that the disassembly and the assembly are convenient.
Compared with the prior art in which the motor is directly used for driving the extruding mechanism, in the embodiment, the motor 210 and the speed reducer 220 are matched to provide torque drive for the stirring auger and the rubber sleeve screw pump. The speed reducer is adopted, the output torque is improved while speed is reduced, and the torque output proportion is multiplied by the reduction ratio according to the output of the motor; in addition, the inertia of the load is reduced while the speed is reduced, and the reduction of the inertia is the square of the reduction ratio.

The rubber sleeve screw pump can directly convert the rotary mechanical energy into the pressure energy of the conveying fluid, thereby extruding the materials. Compared with the method that the screw conveyor is adopted to pressurize the material to be extruded out of the nozzle, the rubber sleeve screw pump is additionally arranged between the front end of the hopper and the nozzle, so that the accurate control of the control module on the material flow can be more facilitated, and the printing precision is higher.
In order to fix the rubber sleeve screw pump, a first fixing plate 401 is arranged at the front end of the stirring part of the hopper, and a rubber sleeve screw pump fixing seat 404 is fixed on the first fixing plate. A second fixing plate 402 is arranged at the lower end of the rubber sleeve screw pump. During specific installation, the rubber sleeve screw pump is fixed on a rubber sleeve screw pump fixing seat 404, a feeding port and a pump shaft are connected, then the second fixing plate 402 is clamped, and the first fixing plate and the second fixing plate are connected and fixed through two (or four) connecting screws 403, so that the rubber sleeve screw pump is stably installed below the hopper.
The torque output by the driving mechanism is transmitted to the stirring auger through the transition shaft and then transmitted to the rubber sleeve screw pump. With continued reference to fig. 5A and 5B, the convex structure 321 at the upper end of the auger shaft is butted with the concave structure 312 of the transition shaft 310 and fixed by the marble cylindrical pin 322; the concave structure 323 at the lower end of the packing auger shaft is connected with the pump shaft of the rubber sleeve screw pump. The concave-convex structure has simple connecting structure and low requirement on an operator; the spring fixing pin has the characteristics of convenience in installation, marble at the end head of the spring fixing pin does not need to be locked in other modes, and any tool is not needed, so that the spring fixing pin can be quickly disassembled and assembled.
